Remifentanil as Intravenous Patient-controlled Analgesia (IVPCA) During Labour

May 22, 2014 updated by: Sorlandet Hospital HF

Remifentanil as Analgesia for Labour Pain

Remifentanil is a ultra short-acting synthetic opioid. It is rapidly metabolized by non-specific blood and tissue esterases. We wanted to investigate the efficacy and safety of remifentanil used as analgesia during labour. Intravenous patient controlled analgesia (ivpca) were used to administer remifentanil. Doses used were 0,15-1,05 mikrogr/kg, with a lock-out time of 2 minutes. 41 women were included in the study. Blood-pressure, heartrate, SaO2, respiration rate and sedation were recorded every 15.minute. Fetal heart rate was recorded for the whole periode of treatment (CTG, STAN). Vaginal contraction pain were assessed by the parturients every 15.minute using a Visual Analogue Scale (VAS). Midwives also recorded their impression of the parturients pain. The parturients level of sedation were recorded by anesthesiologist and midwife every 15.minute. Apgar scores were registered at 1, 5 and 10 min after delivery. Umbilical cord blood analysis regarding blood gases and concentration of remifentanil were performed. After delivery, both mother and midwife evaluated efficacy and safety; Global satisfaction score, if the remifentanil doses were sufficient, nausea, vomiting, level of sedation and dizziness.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Pain Score, Visual Analogue Scale (VAS) (Mean Maximal Change in Pain)
Time Frame: From start with remifentanil treatment until delivery, up to 8 hours.
Continuous Visual Analogue Scale 0 - 100 millimeters (0=no pain, 100=worst imaginable pain) Registration of pain scores before start and every 15.minute during treatment with remifentanil. Result given is the maximal change in pain score (mean) compared to the baseline value at the given timepoints.
From start with remifentanil treatment until delivery, up to 8 hours.

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Patient Satisfaction
Time Frame: From start of remifentanil treatment until delivery
Patient satisfaction with remifentanil pain relief by use of questionnaire answered within 24 hours after delivery. Evalutated by a 5-point scale; 1-very satisfied.......5-very dissatisfied.
From start of remifentanil treatment until delivery
